Spawn container:
|
|
|
|
```bash
|
|
docker run -t -i superboum/arm32v7_postgres:v6
|
|
# OR
|
|
docker run -t -i superboum/amd64_postgres:v1
|
|
```
|
|
|
|
|
|
Init with:
|
|
|
|
```
|
|
stolonctl \
|
|
--cluster-name pissenlit \
|
|
--store-backend=consul \
|
|
--store-endpoints http://consul.service.2.cluster.deuxfleurs.fr:8500 \
|
|
init \
|
|
'{ "initMode": "new", "pgHBA": [ "host all postgres all md5", "host replication replicator all md5", "host all all all ldap ldapserver=bottin.service.2.cluster.deuxfleurs.fr ldapbasedn=\"ou=users,dc=deuxfleurs, dc=fr\" ldapbinddn=\"<bind_dn>\" ldapbindpasswd=\"<bind_pwd>\" ldapsearchattribute=\"cn\"" ] }'
|
|
|
|
```
|
|
|
|
Then set appropriate permission on host:
|
|
|
|
```
|
|
chown -R 102:102 /mnt/storage/postgres/
|
|
```
|
|
|
|
(102 is the id of the postgres user used in Docker)
|
|
It might be improved by staying with root, then chmoding in an entrypoint and finally switching to user 102 before executing user's command.
|
|
Moreover it would enable the usage of the user namespace that shift the UIDs.
|
|

|
## Upgrading the cluster
|
|
|
|
To retreive the current stolon config:
|
|
|
|
```
|
|
stolonctl spec --cluster-name pissenlit --store-backend consul --store-endpoints http://consul.service.2.cluster.deuxfleurs.fr:8500
|
|
```
|
|
|
|
The important part for the LDAP:
|
|
|
|
```
|
|
{
|
|
"pgHBA": [
|
|
"host all postgres all md5",
|
|
"host replication replicator all md5",
|
|
"host all all all ldap ldapserver=bottin.service.2.cluster.deuxfleurs.fr ldapbasedn=\"ou=users,dc=deuxfleurs,dc=fr\" ldapbinddn=\"cn=admin,dc=deuxfleurs,dc=fr\" ldapbindpasswd=\"<REDACTED>\" ldapsearchattribute=\"cn\""
|
|
]
|
|
}
|
|
```
|
|
|
|
Once a patch is writen:
|
|
|
|
```
|
|
stolonctl --cluster-name pissenlit --store-backend consul --store-endpoints http://consul.service.2.cluster.deuxfleurs.fr:8500 update --patch -f /tmp/patch.json
|
|
```
|
|
|
